How Chelsea's Boobs Work (Not Implants)

So you might be suprised to know Chelsea does not have implants. It's my fault I depict her in very tight clothing that disguises her natural shape.

But she is in fact natural! The reason how she came to be this way might vary on the story, but how they actually function as her breasts tends to be the same.

Above is an example of normal breast. and below is of course Chelsea.

So, for a normal breast, fat tends to buffer the single collection of mammary glands that link at the nipple. But for Chelsea, her breasts are built with what I call Fibrous Tissue Sacs, a material similar to tendons, but softer and much more sparse. They keep her breasts firmly connected to her typically stronger pectorals, as well as create an intricate 3D web that has an effect similar to a sponge, where it's capable of keeping a very round shape, even when full of milk. Each sac has its own collection of fat tissue and mammary glands, and while Chelsea has yet to lactate, she possesses the means to create and hold a lot of milk!

Of course breasts this size require a lot of blood, and her circular system has grown to accommodate it. the Fibrous Sacs help keep the pressure in her breasts even, allowing blood to flow naturally without straining her heart.

Not to mention her nerve endings are clustered in far greater numbers, especially around her areolae, making even slight touch very stimulating to her.

So, that's how I envision her boobs. A lot of pseudo-science involved, since it's fictional and all. So don't be suprised if there are any mistakes, seeing as how i'm far from being an expert, or even an amateur at human biology. But I hope this provides some insight on how Chelsea can have such huge, full, perky breasts while still being soft and squishy!
